AUTOMATIC SAFETY TROLLEY.

-App1'ication filed April 30, 1925. seriafm. 26,975.

This invention relates to trolley wheel guards and trolley wire scrapers.

'The invention has for one of its ob ects the provision of a guard which will prev vent. the trolley wheel from accidentally leaving the trolley wire, which will readily open on coming in contact with a trolley wire hanger and close immediately after passing the same, and which may be readily opened manually to permit it to pass the hanger during the backing of the car or to permit the trolley wheel to be drawn down out of contact with the wire.

A further object of the invention is the provision of a scraper which will effectively remove ice fromthe' trolley wire in advance of the trolley wheel, which will readily pass trolley wire hangers, and which can be readily secured to a trolley pole.

The foregoing. and other objects are attained by the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, wherein:

16. drical bodies 19, are secured to the upper ends of the cylinders by pressing said Corresponding and like parts are referred to in the following description, and designated in the several views of the accompanying drawings, by similar reference char{ acters.

In the drawings 1 designates a trolley wire, 2 a hanger therefor, 3 a trolley wheel, and e a trolley pole provided at its upper end with a harp 5. The trolley wheel 3 loosely mounted on a. hollow axle 6 which is gournaled in bearing openings 7 in the arms 8 of the harp 5. The ends 9 of the axle 6 extend laterally beyond the sides 8 of the harp '5 and are reduced and externally screw threaded. I To permit the wheel 3 to be lubricated in the manner hereinafter pointed out, the axle '6 is provided in its outer side with a longitudinally extending groove 10 which communicates with the interior of the axle by way of openings 11. The wheel 3 is maintained in a central position on the axle 6 by springs 12 secured at their lower ends to the arms 8 by screws 13 and contacting at their upper ends with collars 14 mounted on the axle and contacting with the ends of the hub of the wheel.

A cylinder 15 is secured to each end 9 of the axle 6 by a hollow screw threaded boss Nuts 17 having heads '18 and cylinbodies in said ends of the cylinders. The nutslT are provided with double spiral long pitch threads 20, the threads of one of the provided with caps 24: through which the lower ends of the shafts 21 pass, andto said lower shaft ends loops or eyes 25 are secured. The hollow heads 26 of levers 27 are mounted on the lower ends of the shafts 21 between the caps 24: and the eyes or loops 7 25. The levels 27 are fixed to the shafts 21 Ell Iltl
